/l Il ever, being stationary, While the upper ends swing in rounding a curve. In this way no lateral movement is given to the equalizing levers 37 or the bolster. A liberal allowance is made for relative lateral or vsidewisemovement of the center journal box with respect to the side frame for 'facilitating rounding curves.

Preferably the walls of the journal box opening, or at least the lateral walls, are lined with wear plates 39 preferably in the form of steel plates.

It is my intention to cover all modifications oic the invention falling within the spirit and scope of the following claims.

I claim:

l. In a railway car truck, the combination of a journalbox, springs carried by said box on opposite sides thereof, a cap member bridging said springs, an equalizing beam movably mounted on said cap member, and hanger rods connected to' said beam on opposite sides of its center whereby loads are transmitted and distributed to said journal box.

2. In a railway car truck, the combina-` tion of a journal box, springs carried by said box on opposite sides thereof, an equaliy'ing beam operatively associated with said springs ier transmitting loads therethrough, and hanger rods connected to said beam on opposite sides or" its center whereby loads are transmitted thereto. l

3. In a railway car truck, the Combination of va journal box, springs carried directly on said box on opposite sides thereof, and equalizing means operatively associated with said Vsprings for transmitting loads therethrough and equalizing the loads as between said springs.

4;. In a railway car truck, the combination of a journal box, springs carried thereby, and an equalizing beam mounted on said springs for transmitting loads therethrough to said journal box, said equalizing beam equalizing the loads as between said springs.

5. In a railway car truck, the combination of a journal box, springs carried by said box on opposite sides thereof, means bridging said springs, an equalizing beam movably mounted on said bridging means, and means for transmitting loads through said equalizing means, bridge means and springs to said journal box.

6. In a railway oar truck, the combinatie of a journal box, springs carried thereby, means bridging said springs, an equalizing beam pivotally mounted on said bridging means, and means for transmitting the loads to said equalizing beam.

7. Ina railway car truck, the combination of a journal box,`springs Carried by said box on opposite sides thereof, a cap member bridging said springs and having a seat portion, an equalizing beam having a rocker portion seated in said seat portion whereby loads transmitted to said equalizing beam will be transmitted and distributed to said journal box through said bridging membei and springs.
